l/Vith the foregoing 'and' other ohieots in View which will appear as the description proceeds, the invention resides in the combination and arrangement 'ot' parts and in the details oi `conistria;tion hereinafter "'described and claimed. being understood that changes in `the precise embodiment o1. the invention herein disclosed'eanbe made Within the scope oi what is'elaimed, Without departing from the spirit of the in'ven-. tion. A

In the 'accompanying drawings the preferred' -form of the invention has been shown.

In Said drawings: Figure. Lis a plan View of the -cultivator. Fig. 2 is a side elevation thereof. ig. 3 is a section ,on line A--B Fig. 1. Fig.v 4i is a transverse section through a vtooth and through the' means exn' ployed `for attaching it tothe cultivator. Fig. 5 is an enlarged'detail viewlshowing one of the locking devices. Referring to' thelguresby characters of reference 1 designates the draft'beam, there being handles 2 at the real' end thereof. Se

cured to this beam at. any suitable point in advance of the handles is a largecircilar rack 3 which is secured in any suitable manner against rotation relative to the beamv 1. and extends. under the beam. Secured Ato the beam l and extending under the middle portion of the rack 3 is a block 4, this block extending longitudinally under the beam. Pivotally connected to the front end portion .of the block are the lapping innerends of front cross strips 5, each of these strips be ing preferably formed of'metal rolled to l.n shape, the upwardly extending lianges ot -front stripsA the strips eingct away' adjacenttheir inner ends, as shown at 6 in Fig 5v so as not to interfere with the independent angular adjustment of the strips. Pivotall 4 areadditional angle strips 7 `the inner endsv of which lap and are vpivotally. mounted preferably upon the bolt 8 Which extends ytlnongh "the center ofthe rack 3. lPivotally strip v7 so that the eli ifs-.thus'lfree to tejipon .the bolt. Eacrclip -9 tightly es 4the intermediate'fportionof' a' riding therefrom and through the adje# y e .connected te the back portion of the bloek6 spring tooth 1Q, this spring toothibei'ng extended rearwardly and dotvnivardly as shown. The forward end of each springv toothis pivotally'connected 'toene -of the F5 by.' means of a bolt 1 3 or the Eike. Links 14 are mounted onv the outer bolts 13 and also on'the -outer end-bolt 117 shown in Fig. -1,f these links -14 serving to hold .the strips- 5 and 7 'properly` spaced without. sgbj'ecti-ng the springteeth to undesirable strains.v lThe ,l rear cross strips 7 have braces 1li-secured thereon, the ,inner ends of the braces. `lapping and resting on the beam 1- and being 'pivot-ally mounted on the holt E. v z

it it/fili ne apparentlthat'each strip 7 is eonstantiy paraliei with the strip' in front thereof and' saii strips, together with beam 1 and links 1K1., constitute 'parallelograms Furthermore the vteeth l2 are constantly maintained parallel although, by adjusting the strips 5 and 7 angularly about their re'- spectivepivots, these teeth 12 can be caused to move'toW-ard or from eachother although maintaining their parallel relation. Mounted on eachstrip 7', so as to straddle the upstanding fia-ngethereof, isga dog 17 which `is U-shaped in cross sectional contour so as ,to snugly straddle the flange. As the dog is v U -sha})ed, it'w'ill be apparent that two rack engaging edges Will-heproduced at its aced out o new-.aal position so as to disengagc .its :unive end i'rom the rack 3. Said strip 7 is then swung about its pivot bolt until it assumes any desired angle relative to the beam 1 and, during this movement, strip .5

justed, the other strip 7 can be similarly adjusted. Obviously. the strips 7 at the two sides of the cultivator can be'brought to any desired positions relative to each other. In Fig. l the two strips 7 have been shown in alinement end extending diagonaily relative to the beam. bviously, however, the two strips can be extended at right angles to the beam or both o/ them can be arranged so as.

to converge either forwardly or rearwardly.

By providing the clips 9, it becomes unnecessary to perforate the teeth 12 at points between the ends thereof. Thus the teeth are much stronger than would be the case should such perlerations he used.

A cultivator including a beam, a circular rack secured at its center thereto and ext-ending thereunder, front cross strips lapping at their inner ends and mounted to swing ,independently relative to the beam, rear angle strips pivotally connected at their inner ends to the heath in alinelnent with the axis of the rack, each oi' said angle strips having its i ange extended upwardly, teeth piiffotally connected to the cross strips and parallel With the beam, the cross strips at each side of the beam being adjustable angularly independently. of the other cross strips, and means straddling and pivotally connected'to the flange of each rear cross strip for engaging the rack tovhold the cross strip against angular movement. Y

22. A cultivatorv including aY draft beam, a circular rack extending thereunder, a bolt extending through thel center of the rack and the beam, angle strips ivotally mounted on said bolt and exten ing in opposite directions'from the beam, said strips being separately movable upon the bolt, locking elements-straddling the Hangers of the respective strips and normally engaging the rack to hold the strips against movement about their pivots, front cross strips lapping atv their inner endsand pivotally connected to the beam, teeth pivotally connected to the last. named cross strips and extending under thoother or angular cross strips, links connecting the front land rear cross strips at their outer ends, clips pivotally connected to the rear cross strips and einbracing the. teeth', and braces extending over the beam and mounted on the central bolt of the rack, said braces diverging downwardly and being attached to the-respective angular cross strips In testimony that I vclaim the foregoing as my own, -I have .hereto affixed my signature in the presence of` two Witnesses.
